Greetings,
i’m having trouble updating the NodeRed program made by a student before me for the automation & manual control of ventilation system in the building & readings from Energy Meters & Impulse Flowmeters
He is using ModBus / TCP, i have not yet connected the ethernet to the Intel NUC nor am i sure will it work automatically and start reading from that cable to NodeRed on NUC.
I tried setting up a simple button in HA & sensor to see if it’s on off (low speed / high speed)
It looks like this in Node-Red:

Any solutions, tips etc. as it’s my first time with NodeRed would be helpful!
